Hi all, at http://wiki.contextgarden.net/PDF/A I found the following: """"" In ConTeXt mkiv, in order to create such a compliant PDF/A file, one can do as follows: first install (or check that they are present) the following color profiles files default_cmyk.icc default_gray.icc default_rgb.icc ISOcoated_v2_300_eci.icc into tex/texmf-context/colors/icc/profiles of your Context standalone directory. The default_*.icc files are part of ghostscript... """"" So I checked that they are present (CentOS 6.6, GPL Ghostscript 8.70) and I discovered that these files are not present at any ConTeXt (or TeX) installation from TeXlive neither as separate files, nor at file context/colors/icc/context/colorprofiles.xml. Only default_gray.icc is present as a part of ConTeXt installations from our garden. Therefore, I would like to ask (a) where I can find the set of original default*.icc files, (b) what is the reason why these files are not included in the TeXlive and garden installations, (c) if it is possible to add it there for future, and (d) if the produced PDF (with \setupbackend[format={pdf/a-1b:2005}...]) is PDF/a compliant when these icc files are not present and the whole content of the document is only in black (i.e. no grayscale, no colours). Our university decided to be "PDF/a compliant", that is the reason why I am asking. Best wishes, Tomáš
